Hi all, I've created a home-brew, open source fence device based on Red Hat's FenceAgentAPI. The fence device and agent are now well supported by Red Hat and now I would like to extend the support to DRBD. I've come up with a semi-canned two-node cluster using DRBD and Red Hat's cluster suite 3. The one thread left dangling is that, when DRBD detects a split brain, there is no fence action taken or recovery process. I understand that DRBD has the ability to tie into a fence device, and I assume that doing so would help prevent split-brain conditions as one node can fence the other, mark itself as "more" UpTpDate and then invalidate the peer if and when it recovers from the fence action. Is this a correct understanding? Any further information would be much appreciated. :) -- Digimer E-Mail: digimer at alteeve.com AN!Whitepapers: http://alteeve.com Node Assassin: http://nodeassassin.org
